@ganeshie8  @ikram002p

ganeshie8 · Answer

$\large   v = f \lambda = \frac{\lambda}{T}$

ganeshie8 · Answer

its just a relation like speed = distance / time
it holds for all waves

anonymous · Answer

So first one is D

ganeshie8 · Answer

yes!

anonymous · Answer

thank ya , what about second one ??? I think its B

anonymous · Answer

@iambatman

ganeshie8 · Answer

for second one,
use the relation in first question

ganeshie8 · Answer

velocity = wavelength x frequency

ganeshie8 · Answer

^^which property is missing in above relation ?

anonymous · Answer

Amplitude

ganeshie8 · Answer

yup ! amplitude got nothing to do with frequency/wavelength/velocity of wave

anonymous · Answer

but I read another MCQ that confused me 
Many wave properties are dependent upon other wave properties. Yet, one wave property is independent of all other wave properties. Which one of the following properties of a wave is independent of all the others?

a. wavelength

b. frequency

c. period

d. velocity


Answer: D

The speed of a wave is dependent upon the properties of the medium through which it moves, not upon the properties of the wave itself.

sry for late  sarah:O
a bit bze

anonymous · Answer

its ok @ikram002p ^_^
what u think ???

anonymous · Answer

@ganeshie8 ????????

ganeshie8 · Answer

speed of a wave depends on wavelength and frequency of wave

anonymous · Answer

ok what about last one ??? ^_^

ganeshie8 · Answer

so the answer/explanation given by ur text/teacher makes no sense to me yet

anonymous · Answer

i think its Moles :/

ganeshie8 · Answer

Density looks more correct

anonymous · Answer

plz explain it little

ganeshie8 · Answer

saying oxygen has a density of 1000000 particles per m^3 is meaningless

ganeshie8 · Answer

ikram002p · Answer

i think its a couse all of them depends on wavelength

ikram002p · Answer

u cant describe gases  using density

ganeshie8 · Answer

if u fill air in a big container,
it occupies the entire container and density will be less

the density of air depends on the volume of container

so density is not a FIXED property of air

oh :O Thank you so much @ganeshie8 and @ikram002p   ya both are a life saver :D
